Compressed Hydrogen Storage
5.2.2 Compressed hydrogen storage. A major drawback of compressed hydrogen storage for portable applications is the small amount of hydrogen that can be stored in commercial volume tanks, presenting low volumetric capacity. Even at high pressures (over 70 MPa), the compressed hydrogen storage presents low volumetric density (lower than 40 kg H 2 m − 3) (Sandrock, 1999).
Compressed Hydrogen
When compressed, the density of hydrogen at 35.0 MPa is about 23 kg/m 3 and at 70.0 MPa is about 38 kg/m 3. This leads to an energy density of 767 kWh/m 3 (27 °C, 35 MPa). The volume of the storage tank is the biggest challenge, since the density of compressed hydrogen is lower than that of liquid hydrogen.
